Abstract
While mucosal‐based melanomas of the head and neck region are uncommon lesions, when they do arise they usually follow an inexorably aggressive course. Experience with these tumors is, necessarily, limited; as such, well‐worked out treatment protocols for the treatment of such lesions are in short supply. It appears as though mucosal melanomas (MuMs) develop more frequently in the nasal cavity and paranasal sinus region, and less often in the oral cavity. It seems that the incidence of nodal metastasis is significantly lower for sinonasal MuMs than it is for MuMs of the oral cavity; this observation may influence decisions about performing neck dissection as a function of location of the primary MuM. At present, surgical excision remains the mainstay of treatment; however, anatomical complexities within the region can hamper attempts at complete excision. Radiotherapy has not traditionally been relied on for routine treatment of MuM, although some recent reports have challenged this view. Chemotherapy is, at present, employed principally in the treatment of disseminated disease and for palliation. As a diagnostic matter, MuM belongs to the class of tumors that, on light microscopy, may with some regularity be confused with other malignancies (including sarcomas, plasmacytomas, and carcinomas); as a consequence, this is a diagnosis which is often best confirmed by way of ancillary testing via immunohistochemical studies. A better grasp of the best means of treating MuM will likely come only when large referral centers are able to pool their experiences with these uncommon yet virulent malignancies. J. Surg.
